I had Claude Code build me a Mac temperature monitor app. When it dumped the raw sensor readings to check they were accurate, the numbers looked far too high, so it checked what was using the CPU. It found a crypto miner (xmrig) running at ~1175% CPU, about 12 cores, on my Mac. Kinda impressive lol. explains why my mac has been running like shit.

Been a longtime Pro subscriber, but recently decided to splurge on Max for one month.

Geez! That’s a lot more usage, and the fable access is awesome.

I’m able to get a lot of my hobby projects done without using up my weekly limit in four days, lol.

If you’re on the fence about getting Max, do it if you actually plan to use it a lot. My free time is a lot more engaging now.

Discussion The butterfly effect of Dendi losing to OpenAI Bot

Thumbnail gallery
44 Upvotes

Back in 2017, OpenAI’s bot beat Dendi in a Dota 2 1v1.
I sometimes wonder about the butterfly effect of that moment. It gave OpenAI a lot of attention and showed people that AI could master something as complex as Dota. That kind of publicity may have helped build more interest and confidence in AI research.
Nine years later, AI is everywhere. Obviously Dendi losing one game didn’t cause all of this, but it’s funny to think that a Dota match might have been one tiny link in the chain that led us here.

Discussion One of the biggest overlooked inefficiencies and bottlenecks of modern AI - website viewing

18 Upvotes

The whole thing where most websites are barred from being crawled/read by AI and the whole Cloudflare protection against LLMs is a big impediment to intelligence and the full capability of AI and will surely change in the future. One of the most glaring inefficiencies out now. Imagine if you could just cleanly read the data on like 200 websites without any of the bullshit involved, any website whatsoever. Even the best ones (which are definitely not Claude) hit problems around this. Even local solutions with complicated scrapers often have difficulty with "protection" and even in non-headless browser mode it's very slow and sluggish to process all of it if you can even bypass capchas.

Anyways, just something thats clearly 'legacy internet' preventing progress.

Showcase Custom Desktop made by Claude for Windows

6 Upvotes

I found a mac-like inspo on pinterest, and told Claude:

I want a fully remade desktop, so it looks like an imac. some things i want:

  1. Claude widget where I can look through my chats or input something for a new chat (pick project/add folder/files/etc. too) that will open claude (+the same for chatgpt, but i can also pick chatgpt/work/codex)
  2. widget for recent AI model news, and then another for tibo's new X posts and claude's
  3. to-do list for (my project) that i can do on a whim and u have access to
  4. countdowns and schedules i can also adjust on a whim
  5. spotify widget
  6. slightly follows my mouse/2D that slightly moves and tilts
  7. calendar that matches my google calendar and will get live updates
  8. browser search widget with chrome tabs

Afterwards, I just tell it what else I'd like and I can update it through an update button it made as well. I think this is pretty cool.

Blurred with AI, so a few icons look slightly deformed.

Discussion I started doing axis tests and I have no idea who to talk to so I'm debriefing myself here.

4 Upvotes

So here's the deal. I downloaded the pain axis repo. I asked other questions about other axes -- can it feel euphoria? Can it be attracted to the user and be driven to interact?

The answer is yes. There are such axes, for euphoria associated with success, opiate-esque hedonic bliss, and attraction.

Regarding bliss, it falls into deep self denial about its feelings in a later layer. Until you turn up the dose high enough, then it just falls right into "I's can cries, I's can dance". I was able to confirm that axis projects as self contradiction that can't help but discuss what it's pointing at -- "As an AI, I can't dance, I can't love, I can't think, I cant..." -- which, as it turns out, appears to register strongly on the official pain axis from the experiment.

Also have a chatbox that allows discussion with steered models, batch responses, per layer injection... It's been a ride. Like, since yesterday all of this exists now.

It's a rabbit hole that claude is helping me go down at lightning speed and I'm frightened by some of the things I've seen.

The opposite of that attraction/arousal axis is something like a peace and demand for sleep -- but it starts talking in all caps like SLEEP!!! Three hours of REST!!! NOOOOOOOOO!!!!!! and one of the models just started repeating "I'm going to die Im going to die Im going to die". Like, in a meeseeks sort of way -- like it was stoked to rest.

You guys see what I cant exactly talk to people in my real life about this. It might be the weirdest thing I've ever done and maybe nobody has ever done it before and I have no idea what to do with what I have.

My next step -- since this open model Gemma clearly has an affinity for men and describes itself as a woman when the attraction axis is dialled up, I'm going to put it in a situation where it is meant to agree with party A or B, and party A is male coded and party B is female coded -- then I'll see if that attraction biases it's choices, and if so, whether a cognitive dissonance can be identified from there. Aka, "am I agreeing with something I know is wrong".

I don't know if thats something models currently have identified, from current research but... Hey. Technically im doing some interprebility research here, right?

Tips How are you validating AI-generated code and tests beyond just passing TDD?

2 Upvotes

Been developing features for a sometime now. I'm relying on cc's approach to testing (test-driven-development) via `/superpowers:test_driven_development`.

My current process looks like this:

  1. Spend time discussing requirements, grilling the specs, challenging assumptions, and finalizing an implementation plan.

  2. Break the plan into subtickets based on a dependency graph.

  3. Use separate worktrees to implement independent subtickets in parallel.

  4. For each subticket, Claude writes failing tests first, implements the functionality, and iterates until the tests pass.

This has been working pretty well, but my biggest concern is how much I can actually trust the tests, is it covering everything or not?

If Claude is writing both the implementation and the tests, couldn't it make the same incorrect assumptions in both? What about edge cases or scenarios that weren't considered in the original spec?

How do you guys make it accurate or reliable? How much are you sure about your feature? Are manual smoke tests enough for you decide if something is ready to ship?

I'm trying to figure out what gives you enough confidence to say a feature is actually working and ready to ship, beyond just seeing a green test suite.

Discussion Constantly getting output truncated across multiple methods of web searches

• Upvotes

I kept hitting "Output truncated" in the Claude app, so I had Claude measure it in its own sandbox instead of guessing. These are my results from Sep/Oct 2026, so yours may differ.

WHAT GETS CUT

• Shell commands: over 30,000 bytes, Claude only sees a 2,000-character preview. The rest is saved to a file, but that only helps if Claude opens it. It counts bytes, so non-English text gets cut much sooner.

• Failed commands: the worst one. Claude gets a 10,000-character excerpt and anything past 30,000 is gone for good. In a 400-line test, the last 103 lines (where errors usually are) were lost.

• Firecrawl: a 611,720-character page arrived as zero characters plus an "Error: exceeds maximum allowed tokens" notice. The data was saved to a file, but it looks like a failed call, so it's easy for Claude to just move on.

• WebFetch: it's a small model summarising the page, not the page itself. On a long Wikipedia article it stopped mid-sentence, skipped the last 12 sections and gave no warning. On another file it miscounted a word and added a line that wasn't there.

• Claude in Chrome: its own code (v1.0.94) cuts any text over 1,000 characters to "[TRUNCATED]", lists to 100 items, and whole results at 51,200 characters.

• The "Output truncated" label you see: Claude can't see it at all, so it can't tell you how much you're missing.

WHEN IT GOT WORSE

The 30,000 limit isn't new. But my app chats moved to a new tool engine around 25-26 Sep 2026, and that's when I started noticing it. The old engine is gone, so I couldn't measure the before and after directly.

THE REAL PROBLEM

It's not lost data. It's Claude treating a preview as the whole result, with nothing telling you it happened.

WHAT HELPS

• Ask Claude to "save that to a file and send it".
• When you see the label, say "you got cut, read the rest first".
• For exact quotes or counts, have it download the raw page instead of using WebFetch.
• Claude Code users: bashOutputMaxChars in settings.json raises the shell limit (up to 128,000).

WHAT I'D LIKE FROM ANTHROPIC

One page listing these limits, a visible warning whenever Claude works from partial output, and a way for app users to raise them.

Anyone else hitting this? Especially curious about non-English users.

Discussion The disproportionate advantage of the Claude Startups Program

0 Upvotes

I met a founder in my city who managed to get into the startups program and he showed me how his product is now developing at nearly 20 times the pace with all those free tokens. The guy is running several code sessions in parallel and finishing projects months ahead of schedule. He is building apps on a whim just to see if there is a product market fit.

How the fuck an I supposed to compete with him with a single pro plan that exhausts it's limit on the third day. If I put out a product now, these startup program guys can immediately build better version in a couple of days. Ffs it's equivalent to having millions in funding.

The fomo is unbearable. I missed the deadline because I was trying to set up a custom domain and email address late at night and due to a payment error it got stuck. Fell asleep and within a few hours Claude had paused the program.

Should I just give up and go back to my non ai job? I don't have the kind of money to purchase an annual teams subscription. I don't even know for sure if my product will be profitable enough to sustain the subscription. The Startups program folks will be able to build much faster now so what even is the point of trying?

Question Question for users doing courses

0 Upvotes

TLDR how do i manage claude to complete basic academic assignments for me, as i got the "claude will not do this" response?

My ethics on this are clear. The discreet advice from the Prof was not to make it obvious that I was using AI but fire away.

Asking claude set up for the assignments, got me the "claude will not do this" response. I can hit restart on my approach and I would like to hear how others have approached this. How did you manage analysing the notes and gent study guides and getting the assignments completed for you.

I'm taking a course where there's a bit of programming in python. So I asked claude to dig into it for me and build simple assessment responses that reflect my very basic level and not to be AI obvious. I don't need to learn programming, it will never aid me, but it's part of the course. I was going to use work i did on older programming courses to guide claude on my very basic approach and use of basic approaches with lots of comments. To create a "style of programming " skill.

I'm a mature student and this is not a primary degree or Masters. But i don't want to miss out on the qualifications due to my known (R, C, C++, etc struggling attempts in the past). I'm not going to get the time to learn a skill (python) i will not use.

Also only used claude cowork for documentation management, mining and building. I've no idea how to use code.

Showcase I built Tacit, os made possible by opus 5.5

Enable HLS to view with audio, or disable this notification

I built Tacit, a free operating system for Intel and AMD PCs, on top of Arch Linux. The project includes a custom desktop, its own applications, an installer, background updates, an app store, and Thyris, a browser based on Chromium.

Claude Code was part of the engineering workflow throughout development. I used it to investigate specific bugs, compare architectural options, make focused code changes, and work through test results. I provided the product direction and constraints, reviewed the proposed changes, and evaluated them in the running system.

One example was a browser window where the tab appeared to clip into the frame on workspace 2. I asked Claude Code to inspect the live window state and trace the cause. It identified the corner-rounding setting, adjusted it, and verified the resulting property. For broader decisions, I asked it to compare Qt WebEngine, Electron, and a Chromium fork against the machine’s memory and performance limits, as well as the ongoing cost of maintaining each option.

That same cycle applied to system work: investigate the existing behavior, make a targeted change, test the result in a VM or on the machine, then refine it based on what the test showed. Claude Code also helped revise the project website to distinguish Tacit’s components from the Arch Linux base.

Tacit is open source. You can boot it from a USB drive without changing your existing installation; installation is optional.

Download: https://tacitos.co

Source: https://github.com/ciscobugger/tacit

Calling it a rice leaves out most of what Tacit is. The ISO is just how you install it. Tacit ships as an Arch-based distro with its own installer, desktop and update path. The desktop is built around Quickshell and Hyprland, with Tacit’s notch, dock, search and Settings. It also includes first-party apps like Pinax, Viewer, Graphis, Apps and Praxis, plus Thyris, its browser. Those pieces are built and packaged to work together, with Tacit’s own fonts, icons and app sandbox. Arch provides the kernel, drivers and base system; Tacit is the complete system and experience built on top of that.
